In this model the water table will be used as the initial conditions. However, the imported water table data can’t be used because they applies only to elements. They must be imported a second time and applied to nodes.
28.The first step is to activate the water table. Select Model|PHAST Free Surface... Check both checkboxes and click OK to close the dialog box.
29.Because the data for the initial water table will be specified by interpolating among data points, an interpolation algorithm must be selected for the Initial_Water_Table data set. Select Data|Edit Data Sets… and select "Nearest" as the interpolation algorithm for the Initial_Water_Table layer. Click Apply to make the changes in the dialog box.
30.Select File|Import|Shapefile… and select “InitialWaterTable.shp.” (in the "My Documents\ModelMuse Examples\examples\data\Biscayne" folder) In the Import Shapefile dialog box. Check the checkbox for “ZVALUE”, change Evaluated at to Nodes, and check Set values of nodes by interpolation. Set the Data Set for “ZVALUE” to Initial_Water_Table. (The user must set Evaluated at first before it is possible to set the Data Set for “ZVALUE.”) Click OK to close the dialog box. When the warning message appears, click No to continue.
